TYPE-CLEAN ER.

SPECIFICATION forming part of Letters Patent N o. 421,044, datedFebruary 11, 1890.

Application filed July 18, 1889. Serial No. 317,846. (No model.)

To all whom it may concern;

Be it known that I, ALEXANDER T. BROWN, of Syracuse, county of Onondaga,in the State of New York, a citizen of the United States, have inventedcertain new and useful lmprovements in Type-Cleaners, of whichthefollowing is a specification, reference being had to the accompanyingdrawings, in which- Figure 1 is a vertical sectional elevation' of thebrush applied to a type-writing machine. Fig. 2 is a front sectionalelevation of the saine detached from the machine. Fig. 3 is a top planview. Fig. 4 is a front elevation of the driving mechanism detached.

My invention relates to 'the construction and operation of rotatingbrushes, and especially brushes adapted to clean the type of atype-writer, the brush mechanism being detachably connected to thetype-writer.

My object is to produce a detachable brushcleaner in which the brushstands vertically and is adapted to travel around the circle or oval ofthe type-bar basket, cleaning the type in succession, and which can betraveled around one way and then be reversed to travel back to thestarting-point again, thus adapting it for use upon anytype-writingmachine in which the type-bars are normally in a circular or ovalbasket.

My invention consists in the several novel features of construct-ion andoperation hereinafter described, and speciicallyset forth in the claimsannexed h ereto.

It is constructed as follows: A is the top plate of a type-writer, inwhich the type-arms l are mounted in any ordinar57 manner, 2 bcing thepitman-Iod connecting the type-arms to the mechanism for operating them.

3 is a ring, circular or oval, dependent from the top of the machine,and against which the lower ends of the type-arms rest in their pendentposition. The type upon `the type-arms are shown at 4.

B is the supporting-frame. of my cleaner, consisting of bars of suitablelength bent at their outer ends and provided with jaws 5 iitting againstthe top plate at the angle thereof, as shown in Fig. 1. These armstogether comprise a supporting-bracket, and they are provided with acent-ral boss 6, which boss has a central opening to receive thevertical shaft 7 ,upon the outer end of which is mounted the crank S,and upon its lower end a bevel` gear 9 is secured. The shaft 7 is hollowand receives the hanger-supporting rod 10, which 'carries the hanger 11,in which is mounted the horizontal shaft 12, and upon this shaft I mountthe bevel-gear 13, the sprocket-Wheel iit loosely over the shaft 12, andat its lower end with arms 1S, forms a yoke carrying the brush-shaft 19,upon which the brush 2O is secured, and the outer end of the brushshaftcarries a sprocket-pinion 21,'connected to Ythe pinion 14 by the belt22. Upon the hanger 11, I pla'ce a hook 23, and 24 is another hook uponthe arm 16, and 25 is a spring mounted between the twohooks and holdingor supporting the arm 16 in proper position to yieldingly engage thebrush with the type.

At 26 in Fig. 1 l showa stop adapted to engage with the front side ofthe arm 16 and regulate the outward throw of the brush against the type.

It will be observed, iirst, that with the rotation of t-he crank-handle8 and bevel-gear 9 thel gear 13, meshing with 9, will be rotated, andthis will rotate the sprocket 14, rotating the pinion 21, and this willrotate the brush rapidly, the spring 24 holding the brush in yieldingcontact with the type 4; and, secondly, with the rotation of the crank,the pinions 9 and 13, and sprocket 14 the pinion 15 is simultaneouslyrotated, and, engaging with the rim-gear 16, travels around on thatgear,

carrying with it the hanger 11 and bringingthc brush 2O into engagementwith all of the type successively around the basket, and that when therotation of the crank S is reversed the motion of the brush will bereversed, so as to brush the type thepother way, and the travel of thepinion 15 around on the gear 16 will be reversed, so that the type willbe brushed in thereverse order.

W`hat I claim is- 1. A typecleaning brush supported yieldin gly andpendent from a frame supported by the top plate of the machine andineans for rotating the brush in contact with the type, substantially asdescribed.

2. A type-cleaner comprising a frame supported by the top plate of amachine and carrying centrally the Vertical shaft and handle, and gearmechanism connected by a belt to a pinion rotating a brush pendent fromthe main frame and engaging with the type successively, substantially asdescribed.

3. The co1nbination,with the type-ar1ns and type of a type-Writer intheir pendent position, of a brush engaging with the type successivelyand pendent from the inain frame, and means for holding the brush inyielding Contact with the type, and means for rotatin g the brush,substantially as described.

4. A, type-cleaner comprising a main lframe carrying centrally anupright shaft and crankhandle and driving-gear, a rim-gear upon theunder side of the frame concentric with the typearln basket, a pinionengaging with the rim-gear and rotated by the main crank, and a brushrotated by said crank and brought into successive contact with the type,substantially as described.

5. The conibination,wth the type-arms and type, of a brush rotating in avertical plane and brushing the type successively in the direction ofthe length of the typear1ns.

In Witness whereof I have hereunto sctlny hand this Sth day of July,1889.'
